PURPOSE:To save an electric power consumed in a motor by a method wherein both of main driving motor and auxiliary motor are driven at the start, and a power source of the auxiliary motor is turned OFF at the stationary operation. CONSTITUTION:Belts 4, 5 are stretched from pulleys 1', 2' of the main driving motor 1 and the auxiliary motor to a pulley 3' of a driven rotating body 3. At the start, an interruption switch 6 is turned ON first of all and then a main switch 7 is turned ON. Subsequently, when a constant-speed rotation starts and a rotational inertia also becomes satisfactory, the interruption switch 6 is turned OFF and the power source of the auxiliary motor 2 is turned OFF. Whereby the consumed electric power of the motor can be saved. |
